Wouldn’t it be great to open up Nautlius (equivalent to Windows-Explorer in Ubuntu) and be able to open up your terminal in that specific folder by simply right clicking and choosing an Open in Terminal option? Unfortunately this option isn’t set by default. Luckily there are two ways to install this option.

Let’s start by coming up with a formula again.
power(2,-2) = (1/2) * power(2, -1) = (1/2) * (1/2) = (1/4);
power(2,-3) = (1/2) * power(2,-2) = (1/2) * (1/4) = (1/8);
power(2,-4) = (1/2) * power(2,-3) = (1/2) * (1/8) = (1/16);
…
//Until exp == -1
power(base, -exp) = (1/base) * power(base, exp+1);
Workspaces allows you to organize your GNOME Desktop in Ubuntu by creating virtual desktops from which you can place your applications. In my case, I like having two files I’m currently working on my first workspace, my browser in the second, and so on. That way, I only have to switch through the spaces instead of having to bring up the windows individually.
This in turn increases productivity since Workspaces allows you to focus on things that you need to get done, instead of sifting through your applications on simply one screen.
To set up a Workspace you can simply right click on a panel and choose Add to panel and select Workspace Switcher. This by default should add four Workspaces to wherever you clicked on your panel. To change this, simply right click your Workspace Switcher, and choose Preferences
So now that you have them you can switch to them by clicking on them, or preferably by pressing CTRL + ALT + RIGHT, or instead of RIGHT: LEFT, UP, or DOWN would be fine depending on how you set up your rows and columns and where you currently are.

I’ve been using vim (or better yet, gvim) for the better part of my undergraduate programming career and for quite some time I struggled on figuring out how to set the default color scheme for gvim under Ubuntu. Well, now that I figured it out, I wanted to share it with you.
Then after opening the file, add the following lines of code to the file if they don’t exist yet.
Slate (left) and Evening(right)
But why Slate you must ask? Its the one mentioned on all the other tutorials. Yes, I know, but it simply rocks. Just check it out and you’ll understand. If not you can choose from any of these other themes.

Virtual Box is a powerful open source x86 virtualization that runs on Windows, Linux, Mac and OpenSolaris. It supports a large number of guest operating systems such as Windows XP, Windows 7 RC, Ubuntu, Debian, SUSE, Fedora, and Red Hat. VirtualBox is free as well as many linux distributions. So if you haven’t tried any, I’d recommend you doing so.
In simpler terms, Virtual Box allows you to run another OS on top of your currently existing one. If you wanted to try installing an OS without the hassle of dual-booting, or even wanted to install another OS to do some programming since maybe Windows isn’t the best for you, then virtualiziation is one way to go. There is also no way you can harm your computer so its risk-free. If you corrupt a guest OS, simply delete it and try again.
Virtual USB Controllers – Connect a USB device and your virtual machine will recognize it, including USB Flash Drives.
For more features visit Virtual Box Features.
If you want to start, simply download Virtual Box and an OS. I’d recommend Ubuntu since thats probably the most user friendly (or so I think). If you want something else, hit up DistroWatch. Once you have that, setting up Virtual Box with the OS is pretty straightforward. I’ll add a tutorial later on for those who still need help.

Example:
pow(2,3); pow(5,4);
Result:
8 125
if ( exp == 0 ) {
return 1;
}
//Initial value for the result is the base
int result = base;
//Multiplies the base by itself exp number of times
for ( int i = 1; i < exp; i++ ) {
result = result * base;
}
return result;
}
